unable to indent json data - dataplumber - Oct-22-2019

I am trying to print the JSON with proper indentation and sorted keys, but it throws an error.

Need help to fix this

Complete code : 

>>> import json
>>> import time
>>> for n in range(1, 10):
...   data = {'id': n, 't': float("%.3f" % time.time()), 'interest':['photo','tt']}
...   jsonData=json.dumps(data)
...   data = jsonData.encode('utf-8')
...   print(data (indent=4, sort_keys=True))
... 
Error:
Traceback (most recent call last):
  File "<stdin>", line 5, in <module>
TypeError: 'bytes' object is not callable

import json
import time
for n in range(1, 10):
    data = {'id': n, 't': float("%.3f" % time.time()), 'interest':['photo','tt']}
    json_data=json.dumps(data, indent=4, sort_keys=True)
    print(json_data)
Output:
{
    "id": 1,
    "interest": [
        "photo",
        "tt"
    ],
    "t": 1571751206.159

Note that this prints 9 separate JSON strings, not single JSON string

Thanks a lot for your reply.
Can you please let me know what was wrong in my approach ?
I was also doing the same thing but in single line. Isn't that allowed ?

Thanks in Advance.

No, you were not doing the same thing in a single line
indent and sort_keys are arguments that you can pass to json.dumps()
In your snippet data is a bytes object and by using data() you were trying to call the object like a function (not possible) and getting the error and passing these arguments to it
Again, note that this is not single JSON string. in the loop you print 9 separate JSON strings.
I guess you may want it to be JSON array of JSON objects

Thanks for the explanation.

PS : I will keep in mind to keep the code and error in separate tags
